Game Description:

This is a game that you can complete in ten minutes if you know what you’re doing, and can spend a lifetime on if you don’t. Take heart in the fact that there’s a guide on GameFAQs.
Basically, the point of the game is to disable members of the Kimengumi using items and tie them up with rope. Get all five, and you can complete the game. If you feel up to it, you can try and pick bonus items to improve your score, too. However, you will have to avoid the random students roaming the classrooms, because touching them kills you instantly.
Apparently it’s based on an anime and manga series, so I’m sure that if you’ve read or watched it you’ll have a whale of a time with this awful game.
